PR'INTERS REGISTER HOOK Filed March 51, 1930 Patented Apr. 18, 1933 UNITED "STATES WILLIAM F. Baton-ANN, OF CHICAGO, ILLINOIS rnmrnns REGISTER; nook Application filed March 31, 1930. Serial No. 440,232.

This invention relates to improvements in printers register hooks for holding printing plates in position on the base, and more particularly to that type of register hook having jockling means at each end of the body of the 100 Heretofore with hooksof this character it is necessary to operate the locking devices at each end of the hook separately, thereby resulting in two separate and distinct operations, with the result that when a great many hooks are employed, the number of operations of locking and unlocking the hook is greatly v multiplled.

. It is one of the objects of the present in- Vention to rovide in a hook of the character having 100 ing means at both ends thereof, means whereby one of the locking elements will be operated by the operation of the other locking element.

A further object is to provide improved means for securing the plate holding jaw to the body of the hook. V 7

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists 1n the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed and shown in theaccompanying drawing illustrating this invention, and in which Figure 1 is a longitudin'al sectional view of a hook of this character constructed in accordance with the principles of this invention and showing the same applied within a groove in a base, a portion of the base being shown in section.

Referring more particularly to the drawing the numeral 10 designates generally the 5 body portion of the'hook which may be of any desired size and configuration, but is shapedto" fit within the groove 11 of the base 12. a j

The numeral 13 designates generally the 6 'plate engaging jaw adapted to engage and rest against the edge of the plate 14.

Connected to anddepending from the jaw 13 is an extension which is formed integral therewith, a portion of the extension spaced from the free end thereof being reduced as at 15 to form a shoulder 16, for a purpose to be set forth. v r

- The numerals 17 and 18 designate generalmembers 17 and 18 are preferably of angle iron construction, the members having semicircular recesses" 19 "opening through the 1y securing members for securing the jaw 13 to the body portion ofthe hook and these the hook by bringing the edges of the members 17 j and 18 together so that they will engage over the shoulder 16 on the extension 15 andthe shoulder 16 fits within the recessed portion 20 on the lower face'of the'members 17 'and-18. The recesses 19'receive the redu'ced portion 15 of the extension on the jaw and the members 17 and 18 are secured together and to the body portion 10 of the hook in any desired or suitable manner, either by brazing, welding or in'any other'manner so that the jaw 13 will be connected to the body 10 for free rotary or pivotal movement with respect thereto on a vertical axis.

tion of a gear 22 suitably mounted, and this meshes with another gear 23 connected with a shaft 24' and the-gear 23 has connected with it for rotation therewith a lbers 17-18 is recessed as at 21 for the recepa'rack 26 in the groove 11 of the base 12 so that when the gear 22 is rotated the hook will be propelled in the groove 11.

The jaw 13 is provided with an opening 27 therethrough which registers with an opening in the gear 22 so that an implement may be inserted into the gear 22 and rotated in the usual manner.

A locking member 28 is provided at one end of the body and a locking member 29 is provided at the other end of the body.

The locking member 28 is provided with a shank 30 having an angular recess 31 opening through the top thereof. The shank 30 is inserted in a bearing in the body 10 and extends through the body, terminating adjacent the upper surface thereof. A nut or collar 32 is threaded upon the shank 30 from the top of the body and the collar is provided with a shoulder 33 to form a bearing in the members 17 and 18 so that when the nut or collar 32 is screwed uponthe shank 30 the locking member 28 will be mounted for free rotative movement on a vertical axis, which is accomplished by inserting an operating implement into the angular recess 31 in the shank 30.

The locking element 29 is secured to the other end of the body 10 by means of a bolt 34 having a head 35 and a portion 36 of a diameter less than the diameter of the head 35 and greater than the diameter of the shank of the bolt so as to form a shoulder 37 which abuts a portion of the body 10. The bolt 34 projects through the body 10 and also through the members 17 and 18 and anut or collar 38 is threaded thereupon. This collar is provided with ashoulder 39 so that by relatively adjusting the nut 38 and the stem of the bolt 34 the shoulder 37 and the shoulder 39 will prevent the parts from being drawn together to such an extent as would interfere with the free pivotal movement of the look ing element 29, as will be understood.

Thevlocking element 29 is operated by the operation of the locking element 28, and to that end there is provided a connecting link 40, one end of which is bent at an angle as at 41 and enters the locking element 29, the element 29 being provided with a cut away portion 42 so that the link will not interfere with the operation of the element.

The other end of the link 40 is provided with an angularly disposed portion 43 adapted to pivotally engage the locking element 28. 'This element 28 is provided with a horizontal groove or slot 44 opening through the lateral walls thereof, and a slot 45 opening throughthe bottom and one of the lateral faces of the locking element 28 and having communication with the groove 44, so as to permit of the attachment of the end of the link 40 with the locking element 28. This is accomplished by turning the element 28 and the link 40 in such a position with respect to each other than the end 43 of the link will pass into the slot 45, after which it is raised to enter an opening in the locking element -28. The locking element is then rotated with respect to the link 40 so as to cause the link 40 to extend transverse to the slot 45 and enter the slot or groove 44.

It will therefore be manifest that with this construction and by inserting an opcrating implement in the shank 30 of the looking member 28 and rotating it, this rotary movement will be imparted to the locking element 29 and both ends of the body 10 of the hook will be simultaneously locked and unlocked, thereby reducing to a minimum the number of operations necessary to lock and unlock the hook in the base, and at the same time provide a means whereby both ends of the body of the hook will be held seated in the groove 11.

If desired indicating marks 46 may be provided on the end of the shank 30 so as to indicate the position of the locking members 2829.

Considerable diiiiculty has heretofore been experienced in connecting the plate engaging jaws 13 with the body of the hook, and with this improved construction and with the extension 15 formed integral with the jaw, the j aw may be connected to the body of the hook for free swinging movement and firmly hold in position by means of the fastening members 17 and 18.
